We described two examples with misleading presentations to draw attention to the role of clinical cytology as apart of multidisciplinary approach to breast lesions. In the first case--Paget's disease of the nipple, there was no obvious clinical and radiological evidence of breast cancer, while the second case--primary non-Hodgkin lymphoma of the breast imitated advanced breast carcinoma. The question is whether accurate and fast diagnoses can be made without cytological examinations. It must be kept in mind that first-hand clinical information and contact with the patient is necessary in rendering accurate cytological diagnoses.
